Abstract
Design of machine foundations requires the prediction of the dynamic response of the
foundation system at the frequencies of interest. The response is typically quantified in terms
of a number of parameters that include the displacement, the dynamic stiffness, the resonant
frequency, the amplitude at the resonant frequency and the natural frequency. The objective
of this study was to investigate the vertical dynamic response of an embedded foundation
experimentally. It was found that embedment increases the stiffness, damping and natural
frequency of a foundation system, reduces the displacement and resonant amplitude, but that
embedment has very little effect on the resonant frequency.
